SOLD MORE THAN 5000 pcs WORLDWIDE SINCE 2013. No complain so far. Works in the first attempt. Excellent kit for beginners. Used by several makerspaces and schools/colleges worldwide.

Here's a simple do-it-yourself (DIY) FM transmitter kit. You can use this simple DIY kit to transmit your voice or audio to your nearest FM radio.

You can use this FM transmitter/microphone in two ways:

a. Audio transmission using electret microphone: You can transmit your voice to FM radio with the electret microphone. You can also place the transmitter circuit close to any loud speaker so that the microphone picks up the sound and transmits to the tuned FM radio.

b. Audio transmission connecting speaker stereo jack to audio source: For hearing better sound, you may connect it to your computer, ipod or mp3 player using a speaker jack. The audio of your music players get transmitted to your nearby radio.

It comes as a pack of parts kit and can be easily assembled if you can follow the silkscreen indicators (labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes. The kit operates with a 3-9V power supply.

Features:

Frequency Range: 88-108MHZ (Frequency can be changed by moving the adjustable inductor coil).

Operating voltage: 3V-9V.

Transmission range: The transmission range depends upon the length of antenna used. We send a simple 20cm long wire that should transmit signal around 10m inside your room. The signal can be transmitted ever far with longer antenna of length around 50cm. It can transmit up to 100m in open space.

Transmits as described

Indeed a fun project for beginners. I had given up making FM transmitter because of inaccuracy in making the inductor. The best thing about this transmitter is that I didn't have to build the inductor myself. If you could build the other coil inductor the transmission would be much better.
